    "question": "在自定义Gradle插件时，如何为插件定义一个可配置的DSL（领域特定语言）块，例如文档中的 `versionConfig` 块？",
    "options": [
      "通过在 `apply` 方法中调用 `project.tasks.create()` 并传入配置类。",
      "通过在 `apply` 方法中调用 `project.extensions.create()` 来注册一个扩展。",
      "通过在插件代码中直接定义一个名为 `versionConfig` 的静态类。",
      "通过在 `build.gradle` 文件中使用 `ext` 闭包来动态添加属性。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "为了让用户能够在构建脚本中配置插件，我们需要使用Gradle的扩展机制。文档中的代码 `project.extensions.create(\"versionConfig\", VersionExtension)` 正是用于此目的。它创建了一个名为 `versionConfig` 的扩展，其属性定义在 `VersionExtension` 类中，从而允许用户在 `build.gradle` 中使用 `versionConfig { ... }` 闭包进行配置。",
    "source": "文档中「1. 自定义插件开发」-「基础插件开发」部分",
    "hint": "思考一下插件如何向项目（Project）对象添加新的、可配置的属性块。文档中的 `VersionPlugin` 类里有一行关键代码。"

    "options": [
      "id 'java' 和 id 'maven'",
      "id 'groovy-base' 和 id 'nexus-publish'",
      "id 'java-gradle-plugin' 和 id 'maven-publish'",
      "id 'java-library' 和 id 'signing'"
    ],
    "correctAnswerIndex": 2,
    "explanation": "`java-gradle-plugin` 插件简化了Gradle插件的打包和元数据生成。`maven-publish` 插件则提供了将构建产物（包括插件）发布到Maven兼容仓库所需的功能。文档中的 `plugins` 块明确展示了这两个插件的应用。",
    "source": "文档中「1. 自定义插件开发」-「插件发布」部分",
    "hint": "查看插件项目自身的 `build.gradle` 文件顶部，`plugins` 闭包中声明了哪些ID？"

  {
    "question": "在“企业级依赖管理”部分，为了集中管理所有子项目的仓库配置（如私有Nexus），文档推荐在哪个文件中进行设置？",
    "options": [
      "根项目的 `build.gradle` 文件中的 `repositories` 块。",
      "`gradle.properties` 文件中。",
      "`settings.gradle` 文件中的 `dependencyResolutionManagement` 块。",
      "每个子项目的 `build.gradle` 文件中单独配置。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "现代Gradle推荐使用 `settings.gradle` 文件中的 `dependencyResolutionManagement` 块来集中声明仓库。这样做可以确保整个构建中的所有项目都使用同一套仓库配置，避免了在每个子项目中重复定义，是企业级项目的最佳实践。",
    "source": "文档中「3. 企业级依赖管理」-「私有仓库配置」部分",
    "hint": "文档中有一个关于私有仓库配置的代码示例，请注意它的文件名是 `settings.gradle`。"

      "mvn clean install",
      "./gradlew build",
      "gradle assemble",
      "java -jar build/libs/*.jar"
    ],
    "correctAnswerIndex": 1,
    "explanation": "Gradle Wrapper (`gradlew`) 是推荐的在CI/CD环境中执行Gradle构建的方式，因为它能确保使用项目指定的、一致的Gradle版本，无需在CI服务器上预装Gradle。`build` 是一个聚合任务，它会编译代码、运行测试并打包应用，是CI流程中最常用的命令。",
    "source": "文档中「2. Gradle与CI/CD集成」-「GitHub Actions配置」部分",
    "hint": "在YAML配置文件中找到 `name: Build with Gradle` 对应的 `run` 字段。"

    "question": "在“Spring Boot项目配置分析”案例中，`dependencyManagement { imports { mavenBom ... } }` 这段配置的主要作用是什么？",
    "options": [
      "将所有在BOM中定义的依赖项强制添加到项目中。",
      "导入一个Maven BOM（Bill of Materials），用于统一管理相关依赖库的版本，而无需在每个依赖声明中单独指定版本。",
      "创建一个新的BOM文件，供其他项目使用。",
      "将项目的打包格式从JAR切换为Maven BOM。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "BOM（物料清单）是一个特殊的pom.xml文件，它定义了一系列相互兼容的依赖版本。通过 `imports { mavenBom ... }`，我们可以引入这个清单，之后在 `dependencies` 块中添加如 `spring-cloud-starter-gateway` 这样的依赖时，就无需再写版本号，Gradle会自动采用BOM中定义的版本，极大地简化了复杂项目的版本管理。",
    "source": "文档中「6. 案例分析」-「Spring Boot项目配置分析」部分",
    "hint": "思考一下为什么在 `dependencies` 块中引入 `spring-cloud-starter-gateway` 时没有指定版本号。"

  {
    "question": "根据文档中“高级定制与扩展”的示例，初始化脚本（init script，如 `gradle/init.d/corporate.gradle`）的主要目的是什么？",
    "options": [
      "仅为当前项目定义特定的任务和插件。",
      "为在本机上执行的所有Gradle构建应用一套通用的企业级配置，例如统一的仓库或测试配置。",
      "替换 `build.gradle` 文件，成为项目构建的主要脚本。",
      "管理项目的版本号和发布流程。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "初始化脚本是Gradle的一种全局配置机制。放置在特定目录（如 `USER_HOME/.gradle/init.d/` 或项目下的 `gradle/init.d/`）下的脚本会在每次Gradle构建开始时执行，作用于所有项目。这使得它非常适合用来强制实施企业范围内的标准，比如设置内部仓库、统一代码质量插件配置等，而无需修改每个项目的构建脚本。",
    "source": "文档中「5. 高级定制与扩展」-「初始化脚本示例」部分",
    "hint": "文档中提到该脚本配置了 `allprojects`，这暗示了它的作用范围是什么？"

      "Jenkins X",
      "maven2gradle",
      "Spring Initializr"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档明确指出，在从Maven迁移到Gradle的评估阶段，可以使用 `maven2gradle` 工具。这个工具可以读取现有的 `pom.xml` 文件，并尝试将其转换为等效的 `build.gradle` 脚本，为迁移工作提供一个良好的起点。",
    "source": "文档中「6. 案例分析」-「迁移策略实施步骤」部分",
    "hint": "在“评估阶段”的第一个要点中，提到了一个具体的工具名称。"
